2 Claims. 1

This invention relates to window construction and it, has particular reference to sash. control devices for frictionally retaining vertically operated sashesin adjusted positions in the frame, and its principal object resides in the provision of astructural sash design in which is embodied tensionedelements capable of frictional engagement with thew-indowjamb and operating in the; sash-- channels on either side of the sash whereby thelatterissupported at any desired position without the aid of such conventional de vices asweights; bolts, and-the like.

Another object of the invention resides in the provision of a sash construction embracing yieldable channel engaging elements by which the sash is secured against lateral movement in its channel and thus prevented from rattling or vibrating under the force of the wind, and by reason of the improved device, minimize the passage of drafts around the vertical sides of the sash.

A still further object of the invention is manifest in the provision of a sash structure which is especially adapted for installation in frames designed for masonry, and other types of structures, in which no provision has been made for weight wells, thus affording a desirable and practical sash control otherwise unattainable.

Broadly, the invention contemplates the provision of a sash construction of economical design suitable for use in all types of window installations embodying a dual, vertically adjustable sash arrangement, and obviates the necessity for unattractive conventional, and not too dependable, weight and cord assemblies.

While the foregoing objects are paramount, other and lesser objects will become manifest as the description proceeds, taken in connection with the appended drawings wherein:

Figure 1 illustrates the invention installed in longitudinal grooves in each stile of a window sash, portions shown broken away to reveal the rooves.

Figure 2 is a transverse sectional view of a window sash, taken on lines 2--2 of Figure 1, illustrating the invention in operation in the sash channels of the window frame.

Figure 3 is a fragmentary transverse sectional view of one stile showing the invention installed therein and in which a fibrous filler is employed.

Figure 4 illustrates the serpentine spring element in perspective.

Figure 5 is a fragmentary perspective illustration of one end of one of the tensioned shoes, and

Figurefiisa fragmentary perspective illustration of one end of. amodified form of the tensioned shoe.

The invention comprises, primarily, a shoe ll) of. any. suitablematerial, such-as. metal, plastic,

orthelike, formed with three sides, and troughlike-in transverse section, and preferably has its ends I L at least partiallyv closed by turning the extended portions I-Z of its closedside I3 over ;the ends H and providingrounded: surfaces It The shoes ID- are verticallyarranged in spe-,

cially formed grooves I! extending longitudinally of each stile l8 of a window sash l9 so that the closed sides or operative surfaces [3 of the members ID are faced outwardly and engageable with the opposing surfaces 20 of the jambs 2| of the window frame 16 between the stops 22 which define the sash channels l5, as shown in Figures 1, 2 and 3.

The grooves I1 are closed at each end, as depicted. in Figure 1, by routing the grooves so that a portion 23 of the stock remains thereby providing an elongated chamber, closed when the sash I9 is operatively installed in the frame It, thus firmly embracing the shoes It in each of which a spring 24 is encased in the manner shown in Figures 1, 2 and 3.

The springs are preferably of the leaf type and serpentine-like in longitudinal section, as illustrated in Figure 4, providing a bear at each of the arcs 25 on each face and at each end 26 which bears against the ends of the grooves I! provided by the portions 23 of the stiles l8.

The springs 24 are arranged in the shoes [0 and bear outwardly thereagainst, with counterpressure inwardly along the bottom of the grooves ll whereby frictional associations are provided between the surfaces I3 of the shoes l0 and the jambs 2! of the frame IS, the rounded surfaces M on each end of the shoes If! expediting the movement of the members along the sash channels l5. By this arrangement the sash !9 can be arrested in any desired position in the frame 16 without the use of weights and cords, or other conventional devices, an even tension being applied along the entire surface of each sash channel IS.

The invention may be modified, as shown in Figures 3 and 6, to include strips 21, of fibrous or yieldable materials, which are arranged in the shoes 28 of this structure to engage the surfaces of the jambs 2i in the sash channels l5 and function as weather strips to minimize the passage of drafts around the sash l9. Obviously, also, the

frictional association between these fibrous or rubber strips 21 and the jambs 2| is closer than that of the relatively smooth surfaces l3 of the shoes [0.

As illustrated particularly in Figures 3 and 6, each of the shoes 28 are formed with a channel 29 opposite the trough-lik open side 30 of the structure by turning the sides 3| downwardly and then back upon themselves at a. The strips 21 are arranged in the channels 29 and, if desirable, cemented in position. The springs 24 are arranged in the trough-like open side 30 of the members 28 in the same manner in which these elements are situated in the shoes Ill.

The shoes 25 ar also formed with a laterally projecting lug 32 at each end cut from the stock and turned outwardly and directed into the open side 30 providing stops or bearings for the ends 26 of the springs 24. The inwardly turned members l2 of the shoes [0 may also be utilized for the same purpose if desired, the ends 25 of the springs 24 being directed outwardly as opposed to the positions of these members as illustrated in Figure 1.

Manifestly, the structure herein shown and described is capable of considerable modification, by persons skilled in the art, without departing from the spirit and intent of the invention or the scope of the appended claims.

What is claimed is:

1. In a sash adjusting device and weather strip, for a window sash having a longitudinal groove formed in each stile thereof and slidable vertically in a frame, a tensioned member arranged ln each groove, the said members formed substantially H-shaped in transverse section providing opposing channels, a spring arranged in the innermost or said channels, and a weather strip disposed in the outer channels and engageable with said frame.

2. In a sash adjusting device and weather strip, for a window sash having a longitudinal groove formed in each stile thereof and slidable vertically in a frame, a shoe member formed with a pair of opposing longitudinal channels and arranged in each of said grooves, a fiat tensioning spring arranged in each of the inner channels and exerting tension on said shoe member outwardly, and a weather strip in each of said outer channels and engaging said frame under tension of said spring.
